<li>The principle of LED lighting is to use light-emitting diodes. Now there are all kinds of light-emitting diode LED lamp and various color LED lights. LED lights are very energy-saving light bulbs.</li>
</ol>
<p>LED lights made of different materials can emit different colors, such as red, blue, etc.</p>
<ol start="2">
<li>The core part of light-emitting diodes is a wafer composed of p-type semiconductors and n-type semiconductors. There is a transition layer between p-type semiconductors and n-type semiconductors, called p-n. Double heterojunctions and quantum trap structures are usually used.</li>

Apply phosphor on the chip on the blue LED, and finally seal the chip around with epoxy.</p>
<p>Two methods (single-chip type and multi-chip type) can obtain a good tone effect (Ra85) white light. One is to light up red, green, blue (R.G.B) blue-green and yellow-orange 2.3 LEDs at the same time;</p>
<p>The second is to radiate blue or ultraviolet LED excitation light source to excite phosphors.</p>
<p>The first method is not only a defect in the LED driving voltage or luminous output, but also has problems with special temperature or equipment life, and it is still a long way from practicality. The second method is to use a device that drives the circuit and is easy to design.</p>
